Abstract
A magnetic bearing having contactless position stabilization of a supported body which includes a damping and aligning arrangement. This arrangement includes two spaced rotating annular permanent magnets which form a gap therebetween and which are attached to a rotor supported by the bearing. A stationary plate having good electrical conductivity and extending into the gap between the permanent magnets, is cut by their rotating magnetic flux. Mechanical disturbances of the rotor generate eddy-currents in the conductive plate which currents damp out these disturbances. A portion of the plate outside the gap is much thicker than the portion in the gap and provides a very low resistance path for the eddy-currents.
